Restoring surgeons? sense of touch during minimally invasive surgeries
A small, wireless capsule has been developed that can restore the sense of touch that surgeons are losing as they shift increasingly from open to minimally invasive surgery.
During open surgery, doctors rely on their sense of touch to identify the edges of hidden tumours and to locate hidden blood vessels and other anatomical structures: a procedure they call palpation.
